r i. T0 all whom zt may concern:

State ofOhio, have invented a newan'd usefful Improvement in l-lelical Brushes of? which the following `is a:specicatiointhey principle of the invention being herein ex# pllained and the bestmode in which Ihave contemplated applying that principle, soas to distinguish it from other inventions.

cated, to a rotary brush oi' the type in which the brush material is disposed'in more orf less helical fashion about the holderfor body.` rlhe-object of the invention is to provide both an improved helical brush section wherein brush material inthe form 'of' strands is firmly held, and amounting for such a section which will permit oft' the ready attachment orremoval ot the latter, in f or der to changesections or replace a worn one with a new one. To the accomplishment of the foregoing and related ends, the inven-. tion, then, consists of the means hereinafter fully described and particularly pointed out p p l 1 i right` angles towthejbase, so that they' will in the claims.

description set forth` in detail certain mech-r anism `embodying the invention, such dis closed means constituting, however, but'one of various mechanical forms in Which the principle of theinventionmay be used.` c lnsaid annexed drawing i c Fig. 1 is an axial section th rough my iin- ;.irovedbrusli and mounting; `Fig. 2 ris a transverse section thereol taken on tli e plane` iulicated by the line E2---2,l"ig. 1; 3 is a. similar section taken on the planeindlcated by the line SW3, Fig. 1; Fig.` 4t is a broken perspective view illustrating the mannerin which one end of the brush section is attached to the mounting or holder; Fig." 5 is' a view 'similar to 4, but showing the` manner in which the other end of the brush` ing' a 'threaded extension a byn'ieansot" vvp-assin` around i' which V.the brush is attachedto the,y driving spindleor shaft, whatever thejcharacter of i thejlatter. The disks 2 and' 3f areyrabbettedv .about their peripheries to` receive thelcorrespondingvends'ofithe shell 1, and longitudi` nallyextendingbolts orrivets 5 hold such ends iirmly together.` Projecting beyond thel y cylindricalsurfaceof vthe shellV 1 adjacent theend member 3 isl a stud 6 'which prefere.

ably extends diametrically through the shell Such opposite end ofstud, 6 in' 'fact is rive` etedtoone` end of a helical metaljstrip' sof as tofsecurethe same to the shell 1 in a po# 7*()i are ypinsertecl. Such looped bases of `the strands `10 pass around a wire '11 llying without the base 8, wherebyit will 'be seen that the strands aresecurely locked 4in place in thefbase. Such` strands are` then bent at project inV a radial directioniifrom the shell 1.

` lCihe end ,of s tu'd designed toengalge with `the brushlsection isnotched as shown at 12 in Fig.l 1, so as to interiit with" a suit abile laperture 13 in the'corresponding end of such brush section. Att-he oppositeend ont the holder is a second stud 15k, which, however,is oscillatorily held in the shell 1, i. e.

yvvliilefits one end pivotally attached y'to the shell, its other end is slidall'ily held in a,

slOt 15, being notched at 16 to engage with a `suitable aperture 17in `the cnr-responding end oi the brush section base. l c The pivotally attached endo this stud 141; serves also to hold the outer endyofthe helical strip 7 in place on the shell, positive oscillation of the stud' in both directionsbeing provided foi' through the medium of `a ,shouldered bolt 1S rotatably but noty longitudinally movably secured in the shell 1 adjacent ythe stud 14 and *at approximately right angles thereto. The threaded end of ythis bolt engages an internallyl threaded member 19 ,that is pivotally attached tothe stud by meansot an apertured extension 2O thereon. y
